Everything you need to text at scale

Text Blasts (SMS) Industry Dominance

No per-seat SaaS tax. Connect your own provider and broadcast directly from your browser.

Bring Your Own Keys (BYOK)

Connect your own gateway accounts directly — 10 providers: Twilio, Telnyx, Plivo, Vonage, Amazon SNS, Sinch, Bandwidth, Verizon, AT&T, and Broadcom. API keys are stored encrypted locally via AES-GCM on your device—nothing is sent to our servers.

Multi-Number Rotation

Load multiple sending numbers from your provider and route outgoing campaigns via Round Robin, Priority, or Cost-Optimized logic to distribute traffic.

Caps & Circuit Breakers

Set per-number daily limits. An automated circuit breaker detects 5 consecutive failure events and triggers a 5-minute cool-down to shield your sender reputation.

Telnyx Line Type Filter

Filter out undeliverable landlines prior to launch. Carrier lookups are cached locally so you never pay to query the same phone number twice.

Automated STOP Handling

Replies like STOP, QUIT, END, or CANCEL add numbers to your local do-not-text DNC database. Webhook endpoints sync incoming opt-outs down immediately.

Dynamic Composer

Dynamic segment counter monitors Unicode and GSM limits in real time. Vary copy with spintax `{a|b}` and personalized `{{first_name}}` fields.

Pacing & Jitter Engine

DuckDB-backed scheduling dripper manages hourly/daily sending limits. Variable sending speeds and randomized ±jitter mimic natural typing to bypass filters.

MMS & RCS Branded Cards

Attach media, images, and audio links. Send branded verified rich messages on Android/iOS (iOS 18.1+) with automatic fallback to MMS and SMS.

One-Click Test Send

Fire a single test text (or test MMS with your image attached) to your own phone before launch, so you see exactly what recipients see — merge tags rendered, link included.

Live Cost Preview

Before you press Start, see the recipient count, segments per message, and the exact credit cost of the whole campaign at your tier. No surprise bills — ever.

Pause · Resume · Loop

Campaigns drip in the background even with the tab closed. Pause mid-flight, resume where you left off, or loop a campaign on a schedule. Progress survives browser restarts.

Do-Not-Text List Manager

Full suppression control: add numbers by hand, import or export your DNC list as CSV, and watch it grow automatically as STOP replies sync in. Every campaign checks it first.

Real Texts — The Verified Upgrade

Your logo. Your brand name.
A green checkmark.

RCS (Rich Communication Services) replaces the anonymous 10-digit number with a carrier-verified branded sender — your business name, your logo, and a verification badge, right inside the native Messages app on Android and iPhone (iOS 18.1+).

  • Rich cards — hero image, title, description, and tap-able buttons in one message.
  • No 160-character limit — RCS messages don't get chopped into segments.
  • Anti-spoofing built in — verified senders can't be impersonated, so recipients trust the message.
  • Check RCS reach first — preview how many numbers on your list are RCS-capable before you spend a single credit. Capability lookups are cached locally so you never pay to check the same number twice.
Automatic Fallback Chain — Nobody Gets Skipped
RCS rich card MMS + image Plain SMS

Every recipient automatically gets the richest format their phone supports. An old flip phone still gets your text — a modern Android gets the full branded experience. One campaign, zero manual sorting.

MMS Picture Texts

Attach a photo, flyer, coupon, or menu right in the composer. We host the image on a public CDN URL automatically and hand it to your provider — no image-hosting setup on your end.

Pictures Get 2–3× Engagement

A picture message stops the scroll. MMS campaigns consistently out-click plain SMS for restaurants, retail, real estate, and events — anywhere the offer is visual.

Flat Per-Message Billing

MMS and RCS are billed as one flat rich message on your credit balance — no segment math. Your provider's carrier fees are separate and paid directly to them at raw cost.

Sister Product Integration

One List. Email or Text.
One Switch.

TextBlasts.app is built right into EmailBlasts.app. Upload a single CSV directory containing both emails and phone numbers, and use the simple Email | Text toggle at the top of the composer to redirect your campaign.

Email Text

EmailBlasts.app offers robust decentralized features to dominate the email industry, bringing your own mailboxes and email platforms directly to your browser.

Mailbox Rotation

AWS SES & 8 Adapters

FAQ

Frequently Asked Questions

Do my texts route through your servers?

No. Messages are sent by API call from your browser straight to your own provider account — any of the 10 supported gateways (Twilio, Telnyx, Plivo, Vonage, Amazon SNS, Sinch, Bandwidth, Verizon, AT&T, Broadcom). We never see your recipients or message content.

Who is responsible for consent and 10DLC?

You are — you're the sender of record. We provide opt-out tooling and line-type filtering, but obtaining consent and registering A2P 10DLC (and RCS brand approval) with your provider is your responsibility.

How does STOP work?

Replies of STOP/UNSUBSCRIBE/QUIT/END/CANCEL are added to your do-not-text list automatically and skipped on every future campaign. You can also connect an inbound webhook so opt-outs sync automatically.

What's this about RCS?

RCS is the branded, verified-sender upgrade to SMS — your logo, rich cards, buttons, and read receipts — now supported on Android and iPhone (iOS 18.1+). It's rolling out, with automatic fallback to MMS or SMS for devices that don't support it.

What's the difference between SMS, MMS, and RCS?

SMS is plain text, billed per 160-character segment. MMS adds a picture (coupon, flyer, menu) and is billed as one flat message. RCS is the full branded experience — verified sender name, logo, rich card with image and buttons, no character limit. You pick the format with one toggle in the composer; the fallback chain handles the rest.

Do I need to host images somewhere for MMS?

No. Attach the image right in the composer and it's hosted on a public CDN URL for you automatically, then handed to your provider with each send. No S3 buckets, no image hosting accounts, no setup.

What happens when a phone doesn't support RCS?

Nobody gets skipped. Each number is checked for RCS capability (and the answer is cached locally so you never pay to check it twice). RCS-capable phones get the rich card; everyone else automatically falls back to MMS with your image, or plain SMS as the final safety net — all inside the same campaign.

Do credits expire? Are texting credits separate from email credits?

Credits never expire, and there's one shared balance across Text Blasts, Email Blasts, and Screen Blasts. Top up once and spend it on whichever channel the campaign calls for. You're only debited when a message actually sends — paused and failed sends are never charged.

Will I waste money texting landlines?

No — run the built-in line-type check before launch and landlines and invalid numbers are filtered out of the campaign automatically. Lookup results are cached in your local database, so re-checking the same list later costs nothing.

Do I need to carry out expensive Google CASA security audits?

No. Standard sending utilizes restricted send-only API scopes (such as `gmail.send` and `Mail.Send`) which do not trigger Google CASA security audit requirements. CASA audits ($600–$1,200/yr) are only required if you actively opt-in to bounce-scanning features (`gmail.readonly`).
